Both the fill and\nvalidation paths use kvm_memslots(), which unconditionally selects address\nspace 0, even when the vCPU is running in SMM and using address space 1.\n\nCommit 56f17dd3fbc4 (\"kvm: x86: fix stale mmio cache bug\") added the\nmemslot generation to the cache key so that a memslot update could not\nleave a stale entry valid. When commit 699023e23965 (\"KVM: x86: add SMM\nto the MMU role, support SMRAM address space\") added the SMM address space,\nthese helpers were not converted to use the active memslots.\n\nConsequently, an update to the SMM memslots can leave an entry from the old\nSMM address space apparently valid after the vCPU returns to the normal\naddress space. A guest can then cause an access to valid RAM at the same\nGFN to be returned to userspace as KVM_EXIT_MMIO.\n\nCompleting that exit through the VMM's RAM address space writes the backing\npage without going through KVM's write-tracking path. If the page backs a\nnested EPT table, KVM can continue using shadow translations derived from\nthe old contents. The WARN_ON_ONCE() in kvm_mmu_write_protect_fault()\ncatches this invalid cache and memslot combination.\n\nUse the vCPU's active memslots when caching and validating the entry.\nMemslot generations are unique across address spaces, so the generation\nalso distinguishes the normal and SMM views. This matches the MMIO SPTE\ncache, which already uses kvm_vcpu_memslots().\n\nOn an unpatched current-mainline kernel, a regression test that fills the\ncache in SMM and updates only the SMM memslots fails the intended RAM write\nand triggers the kvm_mmu_write_protect_fault() warning. With this change,\nthe same test completes the RAM write without a warning.

no network protocol carries the input.\nAC:L - A malicious L1 can deterministically enter SMM, fault on an unmapped GFN to fill the cache, alter Q35 SMRAM mappings, execute RSM, and write the same GFN; this requires no race, and the complete sequence was reproduced with nested VMX/EPT.\nPR:L - The demonstrated escape needs kernel-level control of the L1 guest to manage SMM and EPT12, but that is tenant-granted guest privilege relative to host KVM; neither kvm_mmu_page_fault() nor vcpu_match_mmio_gen() requires host administrative capability.\nUI:N - The malicious L1 performs the SMM access, Q35 SMRAM reconfiguration, RSM, nested-EPT update, and final RAM write itself, without any action by a host user or administrator.\nS:C - The flaw originates in host KVM's per-vCPU MMIO cache, while stale shadow EPT translations permit the guest to access host kernel memory, crossing the guest-to-host virtualization boundary.\nC:H - Bypassing kvm_page_track_write() leaves EPT02 translations derived from old EPT12 contents; on affected Linux 6.1.74 this exact stale mapping was demonstrated to provide arbitrary reads of host physical and kernel memory.\nI:H - The same stale EPT02 translations were demonstrated to provide arbitrary host-memory writes and host-kernel code execution after emulator_write_emulated() incorrectly routed the tracked EPT12 write through KVM_EXIT_MMIO.\nA:H - Arbitrary host-kernel writes and code execution can crash the host and all co-resident VMs;
